The counter in GPIF II Designer like COUNT_DATA and COUNT_ADDR, are they controlled by the external clock or by cpu ? I recently find the IN_DATA don't coincide with the counter, they work under the different frequencies.

There is a recent bug found in the GPIF because of which this issue happens. This happens when you switch back to back very frequently (ping pong). Also this issue will not be seen if there is the clock frequency is less than 90 Mhz.

We are working on this internally to find a fix / workaround.
